Patented .lune 3, 193@ y iJNrrEDFsrAr-as PATENT ortica f EDWARD B. snLWAY, or LEETsDALn, PENNSYLVANIA ADJUSTABLE METALLIC FORM FO CONCRETE VALLS Application led Januaryv 14,1928. Serial. No. 246,858.

This invention relates to forms for casting reinforced concrete walls and, while the forin may be used in other connections, it'is particularly designed to be used in connection with the steel studding which forms the subject-matter of myapplication f-or patent,

l Serial #235,005, filed on the 22nd dayr `of November, 1927. i

A further object is'to provide a form which f may vbe used either forl forming aV concrete wall surface upon 'the steel studding referredy to and the reinforcing wires carried thereby or mayA be used, for instance, in connection with the form shown in my patent granted on December 6,1927, #1,652,056, for the formation of concrete walls.

A more specific object ofthe invention is to provide a form which is light, which is simple in structure, which is made of metal and thus will do away with the ordinary,

of construction and arrangement of parts as j will appear more fully hereinafter.

panying drawings, wherein :e

Figure 1 is a front elevation of a metallic form constructed in accordance with my invention; l

l Figure 2 is a side elevation of the form, the studding being shown in elevation and the concrete partly in section;

Figure 3 is a like view to Figure 2 but showing the form lifted off the partiallyset concrete;

forms by itself; .Y

Figure 5 is a top plan'view: thereof. l Referring to these drawings, it willbe seen that each unit lofmy improved form consists Myvinvention is illustrated in the accom-v Figure 4 is a-frontr elevation of one of the through oneof the apertures 31, this bolt of the sheet metal body, designated generally 10, having any desired length and width. Attached to the upper and lower margins of the sheet metal bodyor plate are the angle irons 11, the outwardly 'projecting flange of :i5` the upper angle iron being provided with the slots 12 and inward of these slots with the holes 13. The sheet metalplate is further braced by 'medially disposed, downwardly extending angle irons 14 and by the diagonal- 60 ly extending angle irons 15. Attached to the lateral margins of the plate are thev angle irons 16 Vand 17. It is to be noted that the angle irons 11 extend at both ends to the edge of the plate 'and that t-he angle iron -1-7 65 projects beyond the plate. Both the angle irons, 16 and 17 have outwardlyy projecting flanges Iformed, with ay vertical series of bolt. holes 18 and at the lower margin of this outi ,wardlyvprojectin'g flange is formed Vvthe 70 slot 19. l j A H Designed for supporting each. unit is va chain v20 with lthe downwardly divergent chains 21 which extend to the eye-bolts 22, these eye-bolts extending throughV the openings 13 in the upper flange of the unit.v The' cables, chains or other flexible connections 2O may be connected to any suitable hoisting v means. Attached to theupper angle iron 11 are T-shape'd irons 23. These irons have a S0 base 24 and a vertical shank25 vformed with an aperture 26' intermediate the ends of the shank. d The upper end of the shank carries 'a flanged roller 27 vwhich is adapted to bear against the vertical angle irons of the steel S5 studs of the building. f f l l Coacting with the shanks 25v of the mem-r bers 23 are the two outwardly projecting arms 28, each of these yarms or bars being of metal and having abase portion 29 formed 90 with-fourpbolt holes and having the outwardly projecting portion of the arm formed ad# jacent its end with a plurality of aperturesl '30 and adjacent the base with a plurality of apertures 31. kAbolt may bepassedthroughV 95 the hole 26in the shank 25 of an iron 23 and acting as a pivot bolt and .also connecting the form proper to the outwardly projecting arm on that side. A bolt passing through any one of the apertures 3G connects the arm 28 to a downwardly extending brace 32, the lower end ci this brace being slotted, as at 33; A bolt, pin or like connection may pass through this slot 38 and through the slot 19 ot the adjacent angle iron 17.

lt will be seen that the brace 32 may be connected in any one oi the apertures 30 and that the lower end of the. brace may be adjusted up or down with relation to the angle irons 17. At the same time the shanks 25 which support the rollers may be each adjusted so as to bring its aperture 26 into correspondence with any one of the apertures 31. rl`hus the form proper which consists of the sheet metal plate 10 and its bracing angle irons may be disposed nearer'to or further from the studding upon which the concrete is to be cast.

VAs beliore stated, this device is designed to be used in connection with the steel studding which terms the subject-matter of my application tor patent before ref :red to. Each studconsists of a pair of angle irons, designated A, the flanges of which are connected at intervals by cross pieces, the outer flanges et the studs being formed with outwardly projecting tongues a designed to support the horizontally extending reinforcing wires or like members B.

ln the use of the device, the arms 28 are tastened as, for instance, to every other stud.

These may be fastened by pins or bolts passn ing'through the bolt apertures b 1n the studding. The shanks of members 23 are then pinned or bolted to the arms 28, the bolts passing through any one of the apertures 31, and then the brace 32 is attached and so adjusted that it will hold the form proper 10 in parallel relation to the studding. Concre C is then filled in in the usual manner, as shown in Figure 2. Vlhen this concrete has the torni maybe lifted. At this time the lower end of the form is shifted outward,

. as shown in Figure 3, thus bringing the rollers 27 against the outwardly projecting langes ot the angle irons A and the form may be then pulled up for the next course, and so on. lt will be understood that any number ot these terms may be attached end to end by soltspa-ssing through the holes 1S and thus forms extending across an entire wall may be thus connected and these forms raised together to mold each course, and after the concrete has partly set and the forms are ready tor moving, then the forms may be shifted outward, as heretofore explained, so that the wheels bear against the studding and then the torm'raised. rlhus the form will not, scrape against or otherwise disturb the partially set concrete. This form may be so adjusted as to regulate the thickness or' the wall to be cast.

My improved form does away with the use of wood forms and the bracing now in common use where reinforced concrete walls are to be cast. Each section or form is relatively light, thus permitting them to be raised or lowered with a low operating cost. Obviously, the forms or sections may be made of various sizes and each form will have a range ot adjustment permitting itssize to be varied with'n a certain range. It Will be seen that it is only necessary, after a course has become partially set, for the operator to remove the bolts holding the bases of the arms Q8 upon the studding and then the forms may be hoisted by means lo1 the cables or other hoisting connections 2O until they have arrived at the new position and then the arms 28 are again attached at their bases to the studding.

Attention is `called to the fact that the form formed ot the platel() and the angle irons 11, 11i, 15, 1G and 17 is adjustable outward by shifting the bolt 2G into any onel of the apertures 31 so as to build a wall from two inches thick to any thickness desired within the range oi the-apparatus, and that when the are placed together side by side, the angle irons 17 of one plate overlie the adjacent plate 10 and are bolted to angle iron 16 of the next adjacent form. Thus by using two or more forms together at the splice, as shown inA Figure 1, a continuous lorm is made around the building.

Obviously the structure maybe modied in minor ways without departing from the spi 1it of the invention as defined in the ap pended claims.
